I know it’s a lot but I need help didn’t get the material because I’m doing online classes and my WiFi is trash

not sure if that is a b but i beleive it is so

bh+hr=25

move all terms to the left side and set equal to 0. then set each factor equal to zero.

h=

isolate the variable by dividing each side by factors that dont

contain the variable.

r=

x=

isolate the variable by dividing each side by factors that dont

contain the variable.

h=-xy+r

solve for r by simplifieng both sides of the equation, then isolating the variable.

r=xy+h

c

step-by-step explanation:

because of the levels

the answer will be the last one
